Patch testing describes a procedure to help identify what ingredients might irritate a person’s skin. Many skin care products contain chemicals that can cause an allergic reaction when a person applies them to their skin. By performing a patch test at home, a person can determine if a product contains ingredients that may cause a skin reaction.
The American Academy of Dermatology (AAD) states that more than 15,000 substances can cause an allergic skin reaction.
A 2021 study found that personal care products caused irritant contact dermatitis in 28.8% of males and 39.5% of females.
Performing a patch test at home can help people identify cosmetic products or ingredients that may cause an allergic skin reaction.
This article discusses the importance of patch testing, ingredients to look out for, and how to perform a patch test.
